Intellicast
is a commercial weather site on the Internet. One of the best features is a
Java-enabled NEXRAD radar loop of the nation. Clicking on a region of the
national radar loop will bring up the regional radar loop for that part of the
country.

AgriMet, a
conjunction of the words “agricultural” and “meteorology,” is a satellite-based
network of automated agricultural weather stations operated and maintained by
the U.S. Bureau of Reclamation. Several kinds of weather data, primarily of
agricultural interest, are available for the Pacific Northwest and Nevada.

The USGS
provides GIS data for watersheds. Perhaps most useful is its use of HUCs
(Hydrologic Unit Codes). HUCs are the numeric addresses for watersheds used by
the USGS, and the site allows the user to look up the HUC for a specific
watershed.

Vieux Inc.
performs mathematical analysis on NEXRAD radar, determines actual amounts of
rainfall over a watershed, and places the data in a format to be used in GIS.
The GIS data allows rainfall to be calculated in watersheds where no rain gages
exist.

The
TIGER/Line files are a digital database of geographic features, such as roads,
railroads, rivers, lakes, political boundaries, and census statistical
boundaries, covering the entire United States. The database contains
information about these features, such as their location in latitude and
longitude, the name, the type of feature, address ranges for most streets, the
geographic relationship to other features, and other related information. They
are the public product created from the Census Bureau’s TIGER (Topologically
Integrated Geographic Encoding and Referencing) database of geographic
information.

The U.S. Environmental
Protection Agency has a Web page called “Surf Your Watershed” that allows the
user to input a location. In return, the EPA provides a map of the watershed,
water quality information, and water use data.

The U.S.
Army Corps of Engineers Waterways Experiment Station (WES) at Vicksburg,
Mississippi, performs research on many aspects of riverine, coastal, and
environmental systems. Some riverine and coastal hydraulics models may be
downloaded beginning at this Web site address.

This
database provides access to best management practice (BMP) performance data in
a standardized format for approximately 100 BMP studies conducted since the
mid-1980s. The database was developed by the Urban Water Resources Research
Council (UWRRC) of ASCE Environmental and Water Resources Institute (EWRI)
under a cooperative agreement with the U.S. Environmental Protection Agency.

Although
this Web site has a Florida focus, the Stormwater News site provides many links
to related Web sites, publications, conferences, and ongoing stormwater-related
activities. Some publications may be downloaded.

Watershed
Assessment, Tracking and Environmental Results (WATERS) is a tool that unites water
quality information previously available only on individual state agency
homepages and at several U.S. Environmental Protection Agency Web sites. WATERS
links several databases to provide watershed information in a map-based format.

The
Environmental and Water Resources Institute (EWRI) of the American Society of
Civil Engineers (ASCE) is an organization devoted to helping professionals in
their water and environmental-related careers.

Local and Regional Hydrology Links

Many Web
sites exist that address the weather or hydrology of a specific region as
opposed to nationwide. A few representative sites have been listed here. While
they may not be pertinent to the area the reader is in, they often contain
links to other geographical regions and are interesting sites in and of
themselves.

This site
was developed by Rice University to warn of possible flooding in Brays Bayou,
flooding that could have serious consequences for not just Rice, but also for
the Texas Medical Center and other parts of downtown Houston. The site offers
real-time NEXRAD radar, rainfall amounts across the watershed, and stream
flows.

Florida is
divided into five water management districts. The South Florida Water
Management District is the oldest and largest and includes a massive amount of
information about the water and environment of South Florida and the
Everglades.

This Web
site of the Northwest River Forecast Center of the National Oceanic and
Atmospheric Administration is the starting point for retrieval of current
information about surface water conditions, including river stages and flows,
in the Pacific Northwest.

The
Northwest Division of the U.S. Army Corps of Engineers encompasses the
Columbia and Missouri River Basins. A wealth of data and other information
about these watersheds may be obtained, starting at this Web site.

State-of-the-art
statistical software and several simulation models may be downloaded from this
site of the USGS, including software for flood frequency analysis, the HSPF
model, and FEQ (Full Equations Model for river hydraulics). A link to USGS
ground water models and software is provided, from which models such as MODFLOW
may be downloaded.

The U.S.
Environmental Protection Agency Center for Exposure Assessment Modeling (CEAM)
distributes several models and software packages for analysis of environmental
data. This Web site provides access to several simulation models, including
HSPF, SWMM (1994 version), and WASP as well as statistical software and various
reports in electronic format.

The most
current version of EPA SWMM is available at this Oregon State University Web
site. The model download is a cooperative version between Oregon State
University and Camp Dresser & McKee, Inc., and is not an “official” EPA
release.

The
National Weather Service’s FLDWAV model performs dynamic routing of natural and
dam-break floods in natural rivers. FLDWAV incorporates and replaces the NWS
DWOPER model, and is available at this Web site.

Software
related to floodplain definition is provided or linked as part of the Flood
Hazard Mapping activity of the Federal Emergency Management Agency’s National
Flood Insurance Program.

Dr.
Bedient uses the book in teaching his courses on surface water hydrology. More
resources, including powerpoint lectures, spreadsheet hydrologic applications,
a course syllabus, and course project information may be found on the course
webpage, and freely used in designing your courses.
